Glenn is extremely easy to work with and very accommodating. His work is very meticulous which is key for me. Response time was pretty much immediate after sending an e-mail or placing a phone call. He is extremely trustworthy. I will definately use Phase One Construction for future work. I can't say enough nice things about him. I would recommend Glenn 100%.

Project: Hire a Handyman
I have been very impressed with this company and they did a terrific job with removing an old wood desk replacing it with a Bluestone patio. I have found Phase 1 to be knowledgeable, professional and on time. I highly recommend this company.

Project: Hire a Handyman
There were several things I liked - most of all I liked that when I was given a time whether it was for the original quote, a phone call or the work - Phase One showed up in a timely manner. Secondly, the owner was friendly, explained how he would proceed in a way I could understand without being condescending, his workmen were polite, helpful and very professional. I had several projects from fencing, concrete, repair of cedar siding, removal and install of mirrored doors as well as install of a bathroom fan and repair on dormer doors. The work areas were left tidy, debris was removed. Very professional.
